7 PROMAX 3D: STRAY RADIATION MEASUREMENTS
The measurements are given for loading factors which result in the maximum local dose per
current time product. The loading factors include the highest selectable X-ray tube voltage
(i.e. 84 kV).
PMMA phantom with a diameter of 160 mm and a length of 160 mm has been used for the
measurements. The phantom is compatible with the specification in international standard
IEC 60601-2-44. The phantom was positioned in the centre of rotation of the 3D X-ray unit.
The values were measured in the horizontal plane which was at the height of the centre of
rotation of the 3D X-ray unit. The unit of measurement was air kerma per mAs applied to the
X-ray tube during normal use. Values are presented in nGy/mAs and shown separately for 3D
and 3D s sensors.
